FACTURING COMPANY, 01' COLUMBUS, OHIO, A. CORPORATION OF OHIO I DOOR FOR HANGABS AND THE LIKE Application filed May 31,

Owing to the horizontal spread of the planes or wings of a flying machine or the enormous size of a dirigible balloon a hangar or other housing forsuch a device must have a very wide entrance; and because of suchwidth it does not appear to be economically practical to 'provide'such an entrance with a single rolling steel door. A steel rolling door should have vertical guiding and retaining channels for its edges, hence where a pluralit of doors is to be provided for the entrance ot a hangar there is presented the problem of displacing such guiding channels or posts containing one or more of them when the entrance isto be opened. Hangars have been heretofore proposed in which there is a plurality of rolling doors having retaining and guiding posts suspended on a track and adapted to be slid laterallyinto and out of door-margin-guiding osition, and means in connection therewith or operating the door to raise and lower it hence the object of my invention is to provide an improved and simplified construction of such structures and mechanisms.

The invention is embodied in the example herein shown and described, the features of novelt being finally claimed.

of the structure showing the post-sustaining devices at such portion and the door operating means.

Fig. 9 is a detail View partly in section looking to the right at the structure shown in Fig. 7 from the line VIII-VIII of said Fig. 8.

Fig. 10 is a diagram showing the power circuit for operating the doors.

In the views the character 15 designates a portion of the building. Installed upon the front wall of the building above the entrance thereto is a plurality of flexible steel rolling doors 16 adapted to be covered with suitable said rolling doors being of the usual construction with winding assrenon 'ro 'rnE mmmn MANU- shaft 12 and end brackets 13. These rolling doors are preferably counterbalanced as usual in that type, so that each of them can be easily unrolled or rolled up and remains in the rolled up condition when the operation of the winding means is stopped.

Secured to the lintel of the wall at the top of the opening is an I-beam 20, the lower flanges of which constitute tracks extending parallel with the aforesaid hoods and upon which tracks travel two pairs of trolley wheels 25, 25", j ournaled in standards 21. The

standards 21 are secured to a bracket 22 carrying a post 23 having door-guiding and retainin channels 24 along its opposite vertical si es to receive and guide the adjacent edges and margins of two of the doorsor curtains. need two door guiding channels.

The lower end of-the post is supported on a rail 60 secured in the floor,

The intermediate post or posts only the post being provided with a flanged wheel 26 to' travel tracks of the I-beam 20 according to the direction the wheel 29 is turned.

The post 23 carries on its front side a vertical power circuit-controlling and post looking shaft composed of two parts 31 and 32 vertically alined and coupled together by a sleeve 33. The upper and lower ends of said sleeve 33 are internally threaded with threads of different and reversed pitch, the lower thread being of slow pitch, and said threads engaging threads of corresponding pitch on the adjacent ends of the two shaft parts 31 and 32 so that when the sleeve is turned the two shaft parts are moved in opposite directions--the upper part moving up while the lower part moves down or conversely according to the direction in which said sleeve 33 is turned.

The lower end of the sleeve 33 has keyed to it a mitre gear 34, it and the sleeve being supported to rotate in a suitable housing or bracket 35 bolted to the post. Meshing with the mitre gear 34 is mitre gear 36 secured on a horizontal shaft 37 'journaled in said bracket 35 and provided with a handled crank 37 for turning said gear 36.

The two shaft parts 31 and 32 are provided with stop collars pinned thereto to limit the movement of said parts into the threaded sleeve 33. By turning said handled crank 37 the sleeve 33 is turned to raise or lower the shaft parts as hereinafter indicated. The upper end of the upper part 31 is tapered and when projected upward enters a tapered guiding and holding member 13 shown as fixed on the bracket 13, and the lower end of the lower shaft 32 is provided with a cross head 38 having pinned thereto a pair of parallel rods 39, 39,'sliding through eyes in a guiding bracket 40 secured to the front of the post. The lower ends of the rods 39, 39, are also pointed to adapt them, when the post is in proper door receiving position, to enter eyes in a keeper 39 bolted tothe rail 60, as suggested in Figs. 3 and 6, to hold the post firmly in position and prevent movement of it and the door in any direction at the lower end of the post. The lower shaftpart 32isprevented from turning when the sleeve 33 is turned by the parallel rods 39, 39, while the upper shaft part is prevented from turning by means of-a lug 31 on the housing 35 and gltering 0. Ion 'tudinal groove in the threadan 7 Secured to the wall above and in a position parallel to the hoods 17, 17 and 17 of the rolling doors is a shaft 41 (see Fig.1) provided with spur gears at 42, fixed thereto, said spur gears being meshed with the spur gears of the several curtain or door rollers. The shaft 41, in the instance shown, is driven by a suitable motor 45 supported in a bracket attached to the wall above, the motor shaft 46 driving suitable gearing rtion of said shaft part 31 (see Figs. 3

43 and 44 and to directly impel the gear 43 and therefore the other gears 42 and 44.

Any suitable means can be provided for raising and lowering the doors. However it is important where there is a plurality of doors to be operated by power that means be provided which shall insure the operation of all the doors at the same time.

In Fig. 10 I have illustrated diagrammatically an electrical scheme for effecting this result. In said diagram the upper ends of three shaft parts 31 are shown. Above these ends the power circuit 50 is strung; and arranged in a suitable box 51 (see Fig. 4) are circuit closures 52 (see Fig. 10) adapted to be actuated to close the circuit by the shaft parts 31. These circuit closers make a series so that it is necessary that all shall be' closed before the power of the motor 45 is applied to drive the shaft 41. In said diagram Fig. 10 is'illustrated within the broken line rectangle 53, the ordinary Westinghouse magnetic reversing switch for reversing the current in the motor 45 so that the power can be applied to the shaft 41 to either raise or lower the doors. At 54 is an ordinary switch board having ordinary switch operating buttons or levers for causing the opening, or

closing or the stopping of the doors at an intermediate point between the full closed or full open position thereof, there being provided at 55 an ordinary automatic circuit breaker for limiting the movement of the doors at the full open or at thefull closed position. At 56 is the externally operated service switch.

In operation, therefore, when the service switch has been operated to bring in the power it is only necessary to press a button or operate a switch lever to cause the raising of the doors if closed or to lower them if open. When the doors are completely raised the intermediate post or posts can be moved laterally to one end of the entrance to the building so as to clear the doorway for the entry or exit of the machine. When desired the doors can be partially raised and left for the admission of workmen or others to the hangar.

The forms of the parts can be changed without departing from the gist of the invention as claimed.

What I claim is:

1. Means for latching a laterally movable post in door guiding position said means including a shaft composed of two parts vertically alined and having their adjacent ends reversely threaded, a threaded sleeve coupling the-adjacent ends of said shaft parts and engaging the threads thereof, means for turning said sleeve to raise or lower the upper shaft part, said upper shaft part adapted to engage a fixedpart-to prevent lateral movement of said post. i
